The Duties were originally applied in 2008 following the conclusion of an antidumping investigation. The rate of duty imposed on imports originating in Canada was 14.93% and 24.1% for OSB from US.
A sunset review was scheduled for 2013 when it was decided to continue with the duties until 2019 following an application lodged by Sumas Sun'i Tahta ve Mobilya Sanayi A.S., a domestic OSB producer.
On 13 November 2019, the Turkish authorities terminated the duty as it was set to expire anyway.
